Maven 插件描述符未生成

Question

我正在创建一个 Maven 插件，MVN 干净安装构建成功，但没有生成 plugin.xml。

@Mojo( name = "cover",  defaultPhase = LifecyclePhase.POST_INTEGRATION_TEST)
public class RunCoverage extends AbstractMojo
{

    @Parameter( property = "cover.wadl", defaultValue = "test")
    private String wadl;

    @Parameter( property = "cover.endpoints",defaultValue = "test")
    private String endpoints;

    @Override
    public void execute() throws MojoExecutionException
    {
        <somecode>
    }
}

而 pom.xml 是

Maven 全新安装不会生成 plugin.xml

在依赖项目中使用时，出现以下错误

无法为 it.gruppopam.common:end-point-test-coverage:1 (/home/d/.m2/repository/it/common/end-point-test-coverage/1/end-point- test-coverage-1.jar):在 META-INF/maven/plugin.xml -> [Help 1] 中找不到插件描述符
[错误]

Answer 1

首先，我会尝试将包装类型设置为 maven-plugin而不是默认值 jar .此外，我建议使用更新版本的插件(maven-compiler-plugin:3.1)并使用更新版本的 maven-plugin-api(3.0？但不是 2.0)。
